Digging deeper... can these things handle (or be configured to handle) connecting to an access point using CCMP encryption?

I've just dusted off my original kickstarter 2's and 2+'s and have wasted a day doing the wifi dance.

So i've updated a 2 to latest firmware, factory reset it and the wifi flatly refuses to connect to any network. I've tried my regular home router. A mobile phone hotspot, my windows 10 desktop hotspot and a shared AP on an Orange Pi Zero.

All of these I can successfully connect to using esp32 and esp8266 so the wifi networks are configured fine. The problem is clearly with the OO2 firmware.

Thanks for that, it's very much appreciated. Playing with my own firmware is out because I don't have the spare time

I can use a micro to handle power management; an attiny should do the job. I was hoping for a solution that used discrete components though.

I'm doing a project that will be battery powered from a less than 700mAh battery for periods of about 1 hour at a time. It will be completely sealed and inaccessible so the battery will remain connected all of the time and it will be charged either with a usb cable or via an inductive circuit.

The intention was to have a single momentary push button to turn it on (if there was enough power) and it could turn itself off if the battery dropped too low or it was shutdown via the wifi gui.

I want to enable a halt signal on shutdown that I can use to power off the Onion Omega 2's that I have. I have a soft on switch circuit that I want to use for a battery powered device. It works fine. The switch functionality is such that if the lipo is too low it won't enable the regulator and therefore won't power the onion.

To complement that I want the onion to be able to power itself off by setting a GPIO pin high when shutdown is complete.

Exactly the same as this Raspberry Pi functionality...
